Why were japanese-americans sent to internment camps?

Americans didn't want to risk any Japs endangering the lives of other citizens, out of pure fear, they decided to round up the Japs and toss them into camps in hopes of lessening any citizen fear, as well as their own.

At the time, you must realize, World War 2 was currently being raged upon the planet, including Japanese attacks on American and British soil, as shown by the attack on Pearl Harbor. Americans didn't trust their Japanese residents, ending up in their placement in these camps. And Americans probably felt obligated, with what Japans ally, Germany was doing to people.
